Sanders rallied supporters at the State Theater in Portland on Wednesday

Democratic presidential candidate Bernie Sanders rallied supporters in Maine just days ahead of the state's caucuses.

Sanders told more than 1,000 supporters gathered at the State Theater in Portland on Wednesday that people once thought of him as a "fringe" candidate and Hillary Clinton as the "inevitable nominee." He told supporters, "Guess what? She's not so inevitable today."

Sanders won his home state of Vermont, along with Colorado and Minnesota, in Super Tuesday voting.

The Vermont senator has a strong following in Maine. He drew about 7,000 people to a rally at the Cross Insurance Arena in Portland in July.

Sanders isn't the only presidential candidate focusing on Maine. Republican Ted Cruz will hold a rally at Hauck Auditorium at the University of Maine in Orono at 10:30 a.m. on Friday.

Maine's Democratic caucus will take place on Sunday. The state's Republicans will hold their caucus on Saturday.
